warmup RF board in UE

The UE starts the RF board, then immediately try to decode PSS/SSS and compute the analog components frequency adjustment
but the card clock will continue to shift with temperature raising
As PSS/SSS decoding is very long, the clock is quite often wrong (with USRPs) when we start actual coherent demodulation and we fail
the message is 'fail to decode PBCH' looping forever

So, I add a small warmup period to have a more stable clock before decoding PSS

Bartosz made a related MR to not throw Tx in the UE before we decode the network

added 5G-NR label

requested review from @bpodrygajlo

clang-format, please

@schmidtr i don't see where i missed it
